COOKING STOVE OR RANGE.

SPECIFICATION forming part of Letters Patent No. 497,272, dated May 9,1893.

Application filed April 12, 1892. Serial No. 428,894. (No model.)

To @ZZ whom it may concern.:

Beit known that I, GiLns F. FILLEY, of St. Louis, Missouri, have made anew and useful Improvement in Cooking Stoves or Ranges, of which thefollowing is a full, clear, and exact description.

The improvement relates to that class of cooking stoves or ranges knownas three-flue and having a low-down reservoir. In such stoves it hashitherto been the practice to warm the reservoir more orless with theheat proceeding from the diving iiues of the stove; that is, the divinglues communicate with the iiue space containing the reservoir, and theheat as it descends through the diving flues is applied partly to thereservoir. VIn the present construction the reservoir is not heated atthe expense of the oven, but with heat which has passed around the ovenand into the ascending flue, and which otherwise would go to the escape,all substantially as is hereinafter set forth and claimed, aided by theannexed drawings, making part of this specification, and exhibiting adesirable mode of carrying out the improvement, and in which Figure l isa vertical, central, longitudinal section of a cooking stove constructedaccording to the principle of the improvement; and Fig. 2 a view inperspective of the same, the View being from above, and with portions ofthe plates broken away.

Only that portion of the stove which is needed for an understanding ofthe improvement is exhibited.

The same letters of reference denote the saine parts.

A represents a three line cooking stove of ordinary construction savingas modified by the improvement under consideration.

B represents the flue leading from the re place of the stove; C, O', thediving-hues; D the central bottom flue beneath the oven E, and Frepresents the ascending iiue; the escape is at G, and II represents thereservoir, and I the iiue space containing the reservoir.

.I is the end plate of the stove; its portions j, j', respectivelyconstitute the partitions which separate the diving-fines from the iluespace I. An opening j 2, in said end plate opposite the ascending ue,and extending, preferably, from about the level of the oven bottom wellupward to the top of the stove, and the full Width of the ascendingliuc, establishes connection between the ascending flue and the fluespace I.

K represents a deflector. It serves to direct the heat from theascending flue intolthe flue space I. The deflector is, preferablyl inthe form of a plate arranged crosswise in the ascending flue anddividing it into two parts substantially; namely, the lower part, f,which' extends from the iue I) upward to about the level of the bottomof the reservoir, and the upper part, f, which extends from said levelupward to the escape, substantially as shown. The deflector ispreferablyinclined as shown.

The action of the construction is as follows: With the damper M open thecourse of the products of combustion is direct tothe escape in the usualmanner; but when the damper is turned up, as in Fig. l, the course isdownward through the diving lines, thence through the side bottom iluesand into the central bot tom fine D, and thence into the ascending fluein which the heat current encounters the deiiector described; the heatis thereby caused to leave the ascending llue and to enter and circulatethrough the flue space I, and thence it returns into the upper part ofthe ascending flue, and thence to the escape, all as indicated by thearrows in Fig. l. In this manner the reservoir in a cooking-stove orrange can be heated by means of heat which otherwise would pass directlyto the escape and be lost, and by reason of the diving lines or fluebeing separated from the chamber con taining the reservoir, the ovenreceives the full benefit of the heat in the diving lines or line; itwill also be seen that no dampers or parts requiring adjustment areneeded to direct the heat in thus applying it to the reservoir, and theheat is applied advantageously to the reservoir.

I desire not to be restricted to a three-line cooking stove in carryingout the present improvement, as the same can, with such nec= essary andobviousmodiications of construc tion as are needed to adapt it thereto,be embodied in a two-fine stove or in a range.

I claim- In a cooking stove or range having the de- 5 scending ues C,C', and the ascending flue F, provided with an opening j, iny its rear,the reservoir H, placed in the flue space I, and the deflector K,in saidascending iiue F, dividing it into substantially two parts, the 1o lowerpart fr extending upward to about the level of the bottom of thereservoir and the upper part f', extending from said level upward to theescape, whereby the reservoir is heated by the otherwise Waste heat,substantially as described.

Witness my hand this 4th day of April, 1892.
